Title: Heat sink for semiconductor light-emitting element use
Inventor: TOMITA KEISAKU
IPC: H01S5/00
Filed: 1989-04-19
Abstract: PURPOSE:To restrain heat generated at a thin-film resistance from being conducted to a semiconductor light-emitting element and to prevent a characteristic of the element from being deteriorated by a method wherein a structure having a heat resistance is installed between a fused part of the semiconductor light-emitting element and the thin-film resistance part. CONSTITUTION:A modulating signal which has been input from the outside through a lead wire 14 is superposed on a laser diode 11 through a thin-film resistance 112 formed on a fused face, of the laser diode, of a heat sink 12. In this case, a groove 113 which generates a sufficiently large heat resistance so as not to conduct heat generated on one side to the other side is formed between the thin-film resistance part 112 and a fused part of the laser diode 11. Accordingly, heat generated by the thin-film resistance 112 is not conducted to a semiconductor light-emitting element and does not cause a rise in a temperature at a p-n junction part. Thereby, the characteristic of the semiconductor light-emitting element are not deteriorated by the rise in a threshold value of the semiconductor light-emitting element, a drop in an external differential quantum efficiency or the like.

IPC: H01P5/18
Filed: 1995-03-31
Abstract: PURPOSE: To prevent discharge under the vacuum of space and to miniaturize the device by shortening a subordinate transmission line by sealing a main transmission line and the subordinate transmission line inside a dielectric block while housing them in a housing groove in the same shape as these lines. CONSTITUTION: A dielectric block 10 formed by the material of a small dielectric constant is vertically bisected, and a main transmission line 20 and a subordinate transmission line 30 are respectively housed in housing grooves 12 and 13, whose cross sections are equally rectangular, confronted at a prescribed interval. Besides, a dielectric board 40 of a large dielectric constant is force- fitted into recessed housing parts 14 and 15 at the upper and lower parts of housing grooves, and the block 10 is covered with a metallic housing 50 to which coaxial connectors 61a and 61b and coaxial connectors 62a and 62b to be connected to the terminal parts of the main and subordinate transmission lines 20 and 30 are fitted.  In this case, impedance matching between the main transmission line 20 and the coaxial connectors 61 is controlled by selecting the dielectric constant of the dielectric board.

Title: Waste toner recovering device
Inventor: TSUJIMOTO JUN
IPC: G03G21/10
Filed: 1989-04-20
Abstract: PURPOSE:To prohibit a printer from being operated when a waste toner recovering unit is disposed and to prevent printing data from being damaged by permitting a detecting means to generate a signal indicating that the waste toner recovering unit is nearly full with waste toner even if the unit is not inserted in a normal position and repeating the detection with a timer means and stopping the action of the printer with a drive stopping means. CONSTITUTION:Even when the waste toner recovering unit 1 is not inserted in the normal position, a waste toner detecting means A generates the signal indicating that the unit is nearly full with waste toner, and the timer means B repeats the detection, then the drive stopping means D stops the action of the printer. Therefore, even when the waste toner recovering unit 1 is not inserted in the normal position, that can be detected before printing is started. Moreover, an additional sensor detecting the presence or absence of the waste toner recovering unit 1 is not needed. Consequently, valued printing data can be prevented from being damaged under this inexpensive constitution.

Title: Disconnection processing system of ring-shaped data way
Inventor: TANIMOTO MASAYUKI
IPC: H04L12/437
Filed: 1984-05-21
Abstract: PURPOSE:To transmit and receive data normally even at the time of disconnection by sending out a clock as a disconnection identifying signal before it is detected and a transmission line is switched to a loop-back state, at the time of disconnection of the transmission line. CONSTITUTION:When a signal on a transmission line becomes a constant state over a prescribed time or longer, a disconnection detecting circuit 11 decides it to be a disconnection of the transmission line, and outputs a disconnection signal. When the disconnection signal is outputted, a data switching circuit 14 does not output data which has become a constant state but outputs a clock signal to the transmission line through an AND gate AN12, an OR gate OR1, a regenerative repeating circuit 9, a selector 10 and a driver 5 during the time when the transmission line is switched to a loop-back mode. In this way, it does not occur that a station of the downstream side detects a disconnection, and only a station which is the nearest to a disconnection spot is switched exactly to the loop-back mode, therefore, the impossibility of transmission can be avoided.
